OBJECTIVE: Recently, selective termination is employed in multifetal pregnancies, in the presence of an abnormal fetus, or in the complication of twin pregnancies. The purpose of this study is to evaluate effectiveness, safety of the tailored selective termination in multifetal pregnancies. METHODS: This study was retrospective and involved six cases. Indication of termination were 3 cases of structural anomalies (anencephaly, encephalocele, body stalk anomaly), 1 case of chromosomal anomaly (21 trisomy) and 2 cases of monochorionic twin complications (acardiac twin, twin to twin transfusion syndrome). RESULTS: We used KCL injection in 4 cases, they were all confirmed dichorionic twin, and in 2 cases of monochorionic twin, we used alcohol ablation of intra-abdominal umbilical artery in 1 case, and radiofrequency ablation of the cord in 1 case. CONCLUSION: All procedures were successful, and all normal infants were delivered in 3rd trimester. Tailored selective termination in 2nd trimester is effective and safe in abnormal multifetal pregnancies.

OBJECTIVES: To evaluate characteristic computed tomography (CT) and magnetic resonance (MR) imaging findings of granulocytic sarcomas of the head and neck. METHODS: The CT (n=11) and MR (n=1) images obtained from 11 patients (7 males and 4 females; mean age, 23.5 yr; age range, 1 to 69 yr) with histologically-proven granulocytic sarcomas of the head and neck were retrospectively reviewed. Histological confirmation was done by bone marrow biopsy in 9 patients, and/or local biopsy in 4 patients. The imaging findings were analyzed with particular attention to location, size, shape, margin, bone destruction, internal architecture, pattern and degree of enhancement, and multiplicity of the lesions. RESULTS: The masses were most commonly located in the orbital cavity (n=8); other locations included lymph nodes (n=5) and palatine/pharyngeal/lingual tonsils (n=3). The mass sizes varied from a mean diameter of 1.3 to 5.8 cm (average, 2.6 cm). Multiple lesions were found in 6 patients. The shapes of the tumors were ovoid in 12 patients and irregular in 4 patients. Most lesions had poorly-defined margins (13/16) and invaded adjacent bony structures (5/16). On the pre-contrast CT images, the masses were iso- (5/8) or low-density (3/8) in comparison with muscle. The MRI, which was obtained in one patient in this study, showed that the mass was iso-signal intensity on T1-weighted images and iso-signal intensity on T2-weighted images compared to the gray matter of the brain. On the post-contrast CT images, there was homogenesous (n=12) or heterogeneous (n=4) enhancement, with mild (n=10), moderate (n=4), and marked (n=2) enhancement in the solid portions of the lesions. CONCLUSION: Although rare, granulocytic sarcomas arise in various locations in the head and neck area (most commonly in the orbit) in the form of well-demarcated, and mildly- and homogenously-enhancing masses with adjacent bony invasion.

BACKGROUND: Atherosclerotic cardiovascular disease and metabolic syndrome are both rapidly increasing in Koreans due to the new westernized eating habits and the aging of the population. The pulse wave velocity (PWV) reflects arterial stiffness and it may be used as an indicator of atherosclerosis. This study was conducted to investigate the association of the PWV with metabolic syndrome. METHODS: Among 1438 persons who visited the Internal Medicine Clinic or Health Center of a general hospital in Seoul, Korea, 384 adults (age range: 30-69 years old) were selected as study subjects. Those patients with cardiovascular disease or other systemic disease were excluded, but the patients with hypertension and diabetes mellitus were included. Ninety four (25.4%) subjects were classified as patients with metabolic syndrome when jointly applying the WHO Asia-Pacific criteria and NCEP ATPIII criteria. RESULTS: The PWV was higher in the older aged group and in the men compared to the other group. The greater the number of diagnostic criteria of the metabolic syndrome subjects had, the higher was their PWV. After adjustment for age, gender, blood pressure, BMI and fasting blood glucose, a PWV change of 1.0 m/sec increased the risk of metabolic syndrome by 1.31 times (95% CI: 0.81-2.09). The risk of metabolic syndrome was 7.62 times higher among the subjects with a PWV greater than 7.5 m/sec (95% CI: 1.07-54.42), as compared with that of subjects with a PWV less than 7.5 m/sec. CONCLUSIONS: The PWV may independently increase the risk of metabolic syndrome as a non-linear pattern. A prospective study needs to be conducted to confirm the meaning of PWV as a risk factor for metabolic syndrome, and especially to determine the cut off point.

Bronchoplastic lobectomy is a lung-saving procedure indicated for central tumors, for which the alternative is pneumonectomy. We compared operative mortality and complications between bronchoplastic lobectomy and pneumonectomy in lung cancer patients. From March 1993 through December 2005, 1,461 patients were surgically resected for non-small cell lung cancer, including 73 who underwent bronchoplastic lobectomy and 258 who underwent pneumonectomy. Bronchoplastic lobectomy was performed on any lesion that could be completely resected by this technique, whereas pneumonectomy was only performed on lesions that could not be removed by bronchoplastic lobectomy. Operative deaths occurred in 1 of 73 (1.4%) bronchoplastic lobectomy and 26 of 258 (10.1%) pneumonectomy patients (p=0.014). Major complications occurred in 16 of 73 (21.9%) bronchoplastic lobectomy and 58 of 258 (22.5%) pneumonectomy patients (p=1.0). Bronchoplastic lobectomy has a lower risk of operative mortality than pneumonectomy. Although the complication rates were similar, bronchoplastic lobectomy was associated with improved postoperative cardiopulmonary status and a low prevalence of fatal complications after bronchial anastomosis. These findings indicate that bronchoplastic lobectomy is a valuable alternative to pneumonectomy for anatomically appropriate patients, regardless of underlying cardiopulmonary function.

Allergy to latex gloves has been described as an unusual complication during labor. However, IgE mediated hypersensitivity reaction to natural rubber have recently been identified as an international health problem. In this first case report in Korea, latex anaphylaxis during labor is described in an operating room nurse who has been continuously exposed to latex gloves. Because of the increasing frequency of latex allergy, obstetrician should take care and give more attention to the clinical history, as well as be aware of this possibility especially in high risk groups.

PURPOSE: Lymph node metastasis is the most important prognostic factor in colorectal cancer. However, 20~30% of patients with lymph node negative colorectal cancer die of recurrent disease. We investigated whether the detection of micrometastasis is of any clinical significance in Dukes' stage A & B colorectal cancer. METHODS: Ninety patients who underwent curative resection of colorectal cancer from Aug. of 1996 to Jan. of 1999 were entered the study. For examination, we used paraffin blocks of lymph nodes which were metastasis-free by conventional histopathology. After preparation of tissue blocks using the serial sectioning technique, the specimens were stained with immunohistochemical method using anticytokeratin antibody. And the hematoxylin-eosin staining was repeated. RESULTS: We disclosed micrometastases in 15 of 90 cases, mostly located in subcapsular sinuses. And in 8 of 15 cases, we also found metastases in repeated H&E staining. There were no significant relationship between the detection of micrometastases and the depth of wall invasion, the histological grade and the status of lymphovascular invasion. With median follow-up of 15 months, we found no significant difference in recurrence between the micrometasis positive and negative groups. CONCLUSIONS: The result showed that the micrometastasis of lymph node in colorectal caner might increase the risk for development of tumor recurrence. But because of small numbers of recurrent cases and relatively short follow-up period, there was no statistically significant relationship between micrometastasis negative and positive groups.
